ALUSHIELD ™ IHM-2000

CASE STUDY − ALUMINUM HOT ROLLING

 

CHALLENGES


 

A 4-hi intermediate hot reversing mill was producing over 3 million lbs of aluminum per day for can body and end stock, trailer roof, and building products. The alloys rolled were mostly 1XXX, 3XXX, and 5XXX aluminum alloys, and the 60K gallon coolant system used municipal tap water for makeup and maintaining system volume during operation.

The rolling oil used required:

  • Frequent additions to maintain rolling performance during the life of the emulsion
  • Additions of biocide (50 gals/month) to control microbiological problems

Additionally, coolant emulsion was used as a lubricant for the table rolls of the hot line on both sides of the intermediate mill, and a constant re-inoculation of the emulsion with microbiological contamination occurred.

The aluminum producer wanted to convert to ALUSHIELD ® IHM-2000 rolling oil to:

  • Improve lubricity performance on harder alloys
  • Reduce requirement for biocide additions
  • Eliminate need for additive additions to maintain good emulsion

 

THE SOLUTION


 

ALUSHIELD ™ IHM-2000 offers the following benefits:

  • Outstanding boundary and hydrodynamic lubricity performance
  • Superior emulsification performance for stability and consistency of emulsion
  • Low metallic soap formation tendency
  • Excellent corrosion inhibition performance
  • Demonstrated bio-resistance under field conditions
  • Low oil consumption rates
